Arbeider med

Er prosjektleder for det bilaterale samarbeidsprosjektet mellom Norge og Angola.

Tar toktleder jobber på Dr. Fridtjof Nansen. Senest, sommeren 2015 i Det Indiske hav (IOE-2), - så mengdemåling av pelagisk fisk i Senegal og Mauritania.  I April 2016 blir det økosystemtokt i Ghana.

Jobber mye med bruken av data fra Nansen.  Assessment av pelagisk fisk, og utvikling av artikler på data fra toktene.

I tre år har jeg forskningstermin (tre måneder i hvert år)  og jobber da med rekrutteringsmekanismer for Norsk vårgytende sild.

I am currently involved in surveys and assessments of pelagic fish in developing countries. Mainly abundance estimation of pelagic fish by the use of the echo sounding methodology applied in research vessels.  I am also participating in working groups doing assessments of the status and development of fish resources in Africa, and I am giving advice on how these assessments can be used as a basis for fish resources management.

I am project leader of the bilateral cooperation programme between Norway and Angola.

Participate in various surveys onboard Dr Fridtjof Nansen, - the most recent once beeing the Indian Ocean survey (July 2015), Acoustic abundance estimation of pelagic fish in Senegal and mauritania (November 2015), and will do an ecosystem survey in Ghana in April 2016.
